ITEM 4.  DESCRIPTION OF SECURITIES.

Not applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Registrant's Certificate of Incorporation, as amended and restated to
date, relieves its directors from liability for monetary damages to the
fullest extent permitted by Delaware law.  Section 145 of the Delaware
General Corporation Law provides, in effect, that any person who was or is a
party or is threatened to be made a party to any action by reason of the fact
that he is or was a director, officer, employee or agent of the Registrant
may and, in certain cases, must be indemnified by the Registrant against
judgments, fines, amounts paid in settlement and expenses (including
attorneys' fees) reasonably incurred by him as a result of such action, and
against expenses (including attorneys' fees), if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the
Registrant's best interest and with respect to any criminal proceeding in
which such person had reasonable cause to believe his conduct was unlawful.
This indemnification does not apply, in a derivative action, to matters as to
which it is adjudged that the director, officer, employee or agent is liable
to the Registrant, unless upon court order it is determined that, despite
such adjudication of liability, but in view of all the circumstances of the
case, he is fairly and reasonably entitled to indemnity for expenses, that
the court deems proper.

Article Six, Section 2 of the Registrant's Certificate of Incorporation, as
amended and restated to date, provide, in general, that no director of the
Registrant shall be personally liable for monetary damages for breach of the
director's fiduciary duty as a director, except for liability for (i) any
breach of the director's duty of loyalty to the Registrant or its
stockholders; (ii) an act or omission not in good faith or an act or omission
that involves intentional misconduct or a knowing violation of law; (iii) any
liability under Section 174 of the Delaware General Corporation Law
(pertaining to unlawful payment of a dividend or an unlawful stock purchase
or redemption); or (iv) a transaction from which the director received an
improper personal benefit.

Article Ten of the Registrant's Certificate of Incorporation, as amended and
restated to date, and Article Six of the Registrant's Bylaws, provide, in
general, that the Registrant shall indemnify its directors and officers under
the circumstances defined in Section 145 of the Delaware General Corporation
Law and gives authority to the Registrant to purchase insurance with respect
to such indemnification.

The Registrant has entered into separate Indemnity Agreements with each of
its directors and certain of its executive officers (each, an "Indemnitee"),
under which the Registrant will, upon proper request of the Indemnitee,
indemnify any Indemnitee if such Indemnitee is a party to or is threatened to
be made a party to or is otherwise involved in any third party proceedings or
proceedings by or in the right of the Registrant to procure a judgment in its
favor by reason of the fact that the Indemnitee is or was a director and/or
officer of the Registrant or is or was serving at the request of the
Registrant as a director, officer, employee or agent of another corporation,




partnership, joint venture, trust or other enterprise, against all expenses,
judgments, fines and penalties, actually and reasonably incurred by the
Indemnitee in connection with the defense or settlement of any of such
proceedings; provided that (i) in the case of a third party proceeding, the
Indemnitee acted in good faith and in a manner which the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Registrant, and in the case of a criminal proceeding, in addition, that the
Indemnitee had no reasonable cause to believe that his conduct was unlawful,
(ii) in the case of a proceeding by or in the right of the Registrant, the
Indemnitee acted in good faith and in a manner which the Indemnitee
reasonably believed to be in or not opposed to the best interests of the
Registrant and in which the Indemnitee shall not have been adjudged to be
liable to the Registrant for negligence or misconduct in the performance of
the Indemnitee's duty to the Registrant, unless the court in which such
proceeding is brought determines that the Indemnitee is fairly and reasonably
entitled to indemnity for expenses as such court deems proper, and (iii) in
the case of a proceeding by or in the right of the Registrant, the Indemnitee
is only indemnified against expenses and not against any judgment, fines or
penalties. Notwithstanding the above, the Registrant shall indemnify an
Indemnitee for all expenses incurred in connection with any proceedings to
the extent that the Indemnitee has been successful in defense of any such
proceeding, or in defense of any claim, issue or matter therein. The
Registrant will also, upon proper request of the Indemnitee, pay in advance
the expenses incurred by the Indemnitee in any of the above proceedings, if
the Indemnitee shall undertake to repay such amounts to the extent it is
determined that the Indemnitee is not entitled to indemnification.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

Not applicable.

ITEM 9.  UNDERTAKINGS.

The undersigned Registrant hereby undertakes:

(1)  To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement: (i) to include any
prospectus required by Section 10(a)(3) of the Securities Act; (ii) to
reflect in the prospectus any facts or events arising after the effective
date of the Registration Statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a
fundamental change in the information set forth in the Registration
Statement; and (iii) to include any material information with respect to the
plan of distribution not previously disclosed in the Registration Statement
or any material change to such information in the Registration Statement;
provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the Registrant pursuant
to Section 13 or Section 15(d) of the Exchange Act that are incorporated by
reference in the Registration Statement.

(2)  That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof;

(3)  To remove from registration by means of a post-effective amendment any
of the securities being registered that remain unsold at the termination of
the offering; and

(4)  That, for purposes of determining any liability under the Securities
Act, each filing of the Registrant's annual report pursuant to Section 13(a)
or Section 15(d) of the Exchange Act that is incorporated by reference in
this Registration Statement shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona fide
offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers, and controlling persons of the
Registrant pursuant to the provisions described in Item 6 of this
Registration Statement, or otherwise, the Registrant has been advised that in
the opinion of the Commission such indemnification is against public policy
as expressed in the Securities Act and is, therefore, unenforceable. If a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer, or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final
adjudication of such issue.




                                 SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant

requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Richardson, State of Texas, on the 12th day of
